SPECIFICATION forming part of Letters Patent No. 790,455, dated May 23, 1905.

Application filed July 1, 1904. Serial No. 214,923.

To a, whom it may concern:

Be it'known that I, RICHARD PFAFF, asubject of the German Emperor, residing at Zurich, Switzerland, have invented. certain newv and useful Improvements in Bottling-Machines, of which the following is a specification.

This invention relates to improvements in bottling-machines. 7

For filling liquids into bottles, especially those liquids which contain carbonic-acid gas and are thus under pressure, it has hitherto been usual for the purpose of pressing the opening in the bottle-neck against the charg ing-pipe to use pedal operated levers or springs acting on the base of the bottle and levers arranged in connection with the fillingcock adapted to engage the neck of the bottle,

also rods guided by eccentric cam-grooves.

All these devices have considerable disadvantages. The pressing of thebottles by means of pedal-levers requires careful attention, and

the opening and closing of the cock by hand is necessary for filling each bottle. These disadvantages are only partly removed with the bottling-machines provided with springs,

since the bottle must also be held by hand in greater force to work them, owing to the greater frictional resistance.

For preventingthe formation of froth during the bottling of liquids containing carbonic-acid gas air under the same pressure as the liquid is first supplied to the bottle,

said air escaping from the bottle by thesame way by which it entered when the liquid flows into the bottle. During this process small quantities of liquid are liable to enter the airchannel, where they remain after the closing I of the cock, and on reopening the latter cause mits of easily adjusting the bottle in the pressing device, and on moving back the bottleholder into the position in which the bottle is filled the pressing or gripping of the bottle is effected. The bottle thus arrives in the filling position after leaving the position at which the pressure is greatest, being held fast in said filling position and an unintentional backward movement prevented. The inconvenience of formation of froth when bottling is removed by providing two air-passages, the passage for entrance of the air under pressure into the bottle being separate from the outlet-passage for said air from the bottle, so that the air enters the bottle during the initial rotary movement of the cock-spigot in the action of opening the cock, whereas said air escapes in the known manner while the cock is open through a separate tube surrounding the filling-pipe. The entrance of air thus takes place at the level of the mouth of the bottle; but the'outlet of air takes place at the end of the said tube, which lies a little way within the bottle-neck. Any frothing of the liquid which tends to return with the expelled air passes up the tube and does not enter the orifice through which the air entered the bottle. For the purpose of guiding the air under pressure into the bottle during the .rotary movement for the purpose of opening the cook a passage is made in the cock, which is opened and reclosed when the passage for theliquid is about to be opened, but before the said opening actually takes place. Both the air-passages and the liquid-passage terminate in a tubular part, which carries the filling-nozzle for the purpose of easily mounting and dismounting the cock.

In the annexed drawings one form of construction is shown as an example.

Figure 1 is a front elevation of a bottlingmachine with a bottle inserted, certain parts being broken away. Fig. 2 is a side view thereof, partly in section and on a larger scale, the out-of-action position of the fillingtube being shown in dotted lines and the tilling position with the bottle against the filling-nozzle being shown in full lines. Figs. 3, 4, and 5 are sections on a still further enlarged scale of the filling-cock.

The reservoir p, mounted on the frame 70, is connected to the cock-casing c by means, of a connecting-pipe 7i and above said casing c the bottle-holder is suspended from the standard q. The bottle-holder consists of arearwardlybent part a, bifurcated at its upper end, the rearward bending being for the purpose of allowing the bottle-plate to be brought to its position of rest immediately below the cook. The bottle-holder also comprises a rod 6, connected to the lower end of part a and on which a sleeve n is adapted to be adjusted, said sleeve being connected to a second sleeve cl, and a rod f, carrying the bottle-plate c and adapted to slide in said sleeve (Z. A spring g between the bottle-plate c and the sleeve cl and surrounding the rod f serves to compensate for dilferenees in height of the bottles.

The bottle-plate 0 can be moved downward against the pressure of the spring g by means of a lever z'eXtending through a slot in the lower end of the rod f and pivoted to the aforesaid sleeve 11 so that the distance of the plate a from the tightening-ring 0 at the neck of the bottle is relatively increased. The handle of the lever 2' serves for operating the bottle-holder.

The cross-bar in, acting as a stop or abutment for the bottle-holder, is so arranged on the frame that the bottleholder can be rotated beyond the point of greatest pressure.

The cock-easing c is provided with three channels tr 5 for the liquid to be bottled and the air, which channels extend through the pipe 7i, connecting the cock to the reservoir 19. The cock-spigot w has a channel 00 in communication with the channel t, said channel r0 terminating in a hollow space or chambers, which is in communication with lateral apertures 11 in a prolongation 7 of the filling-nozzle 8, by means of a channel a. These channels form the passage-way for the pressure-air from the reservoir to the bottle. The spigot w is also provided with the channel 0 in communication with channel 0' and leading to the lateral apertures 9 in the prolongation 7, said channel a being for the passage of the liquid, and finally a channel 2 in communication with channels 5 and leading to the apertures 10 of the prolongation 7 said channel 2 being for the return-passage of the pressure-air from the bottle to the reservoir. Tubes (3, (one of which only is seen in Figs. 2 and 3, the other being immediately behind it,) connected to the channels 25 and 5, permit the passage of the air through the liquid contained in the reservoir 1) into the upper air-space of said reservoir.

In the prolongation 7 is arranged the lillingtube 1, communicating with the apertures 9, and surrounding said filling-tube is the airoutlet tube 3, having lateral openings I and communicating with the apertures 10. Between the outlet-tube 3 and the prolongation 7 and ring 8 is an annular space .2, communicating with the apertures 11 and through which the pressure-air passes into the bottle at 0.

The outer ends of the channels 1:, w, and 2 are in such positions that when the cock-spigot w is rotated by means of the tubes 1 and 3 the channel 00 is first placed in communication with channel 2,, and the air under pressure onters the bottle. On further rotation this passage is closed and the passages for .the inlet of liquid and outlet of air are opened, channel w arriving in communication with channel u and channel 2 with channel 5.

The bottle to be filled is placed over the H11- ing-tube 1 and on the plate a, which is previously pulled forward and is rotated, with the bottle-holder, toward the stop or abutment m, which rotation opens the cock. After hottling the whole bottle-holder is again pulled forward. the cock being thus closed, and the bottle is then removed.

In a bottling-machine, the combination of a reservoir containing liquid and air under pressure, a charging-cock adapted. to be placed in communication with said reservoir, a pivoted filling-nozzle in communication with said cock and having means for inclosing a bottleneck, an oscillatory bottle-holder having its point of suspension above the axis of the cock, a spring-pressed bottle-plate carried by said holder, and a stop for holding said bottle-holder in a position beyond the point of greatest pressure, for the purpose set forth.
